Boy have you come to the right place...funny thing is everyone has a different opinion
But that is what makes YT so much fun and so great! A few sites to help you get started on what will probably be a long road, if your Yorkie is like most...picky
are:
THE DOG FOOD PROJECT
The Dog Food Project - Identifying better products and
Dog Food Analysis - Reviews of kibble
I have no experience with Eukanuba but did use RC for Yorkies for about three months. My girl liked it but she started scratching a lot and licking her paws, signs of food alergies. So now I am using California Natural limited ingredient. Many, Vivian this is you, have talked me into feeding raw as well. I will start Maddie on this in a few days in the evenings, and keep kibble in the morning.
GOOD LUCK!!
